Tyler Hubbard, wife Haley expecting second child: 'So thankful'

Feb. 11 (UPI) -- Florida Georgia Line singer Tyler Hubbard is going to be a dad of two.

The 32-year-old recording artist confirmed in an Instagram post Sunday that he's having another baby with wife Hayley Hubbard.

Hubbard shared a photo of himself kneeling and kissing Hayley's baby bump at the Clive Davis pre-Grammy gala Saturday. The expectant mom wore a strapless pink gown to the event.

"The Hubbard family is growing. We are excited to share that little nugget #2 is on the way," Hubbard captioned the post. "We are so thankful and can't wait to see Olivia be a big sister. What do y'all think.... boy or girl?"

Hubbard and Hayley are already parents to 13-month-old daughter Olivia Rose. Hayley confirmed her second pregnancy with a photo featuring Olivia on Sunday.

"Thrilled to finally share that Olivia will be a big sister in August! We couldn't be more excited and grateful!!!!" she wrote.

Hubbard and Hayley stepped out together Sunday to the 61st annual Grammy Awards, where Florida Georgia Line was nominated for Best Country Duo/Group Performance for "Meant to Be" with Bebe Rexha.

"We decided yesterday that we might as well go ahead and let everybody know that we're expecting our second child," Hubbard told People on the red carpet. "We're super excited and super thankful."

Florida Georgia Line is a country music duo composed of Hubbard and Brian Kelley. The duo will release their fourth studio album, Can't Say I Ain't Country, on Friday.
